Best makes JavaScript look like Java, it’s needlessly complex and just encourages vast amounts of boilerplate. Awful stuff.
My go-to right now is itty router with zod.
Btw, itty-router v5 just dropped a couple days ago, with a fun batteries-included (still ultra-small) router, that should make your code even leaner.
How is the integration w/ zod anyway, and how can we make it better?
I'm in the progress of making a simple middleware based on zod to parse not only request body, but also params, headers, etc. Zod is really powerful and you could even use it to do stuff like parse jwt tokens and have complete type inference.
Perhaps my only issue with this approach is that you rely on a wrapper function to correctly pass the generics fron the middleware to the main handler.
Another possible approach is using types-per-route but then it's hard to enforce that the validator agrees with the handler itself.
Provider initialization (dependency injection) failed on me on a few occasions and it always wasted hours of productivity. It would break in some obscure way that wouldn't log any errors to the console, so there was nothing to go on besides attaching a debugger and stepping through layers of framework code. It was quite infuriating because it always happened when I was in the middle of something else.
If your specific use case wasn't covered by their docs (which were very barebones and "hello-world" oriented at the time), it was painful to figure out and use.
